TO MARY W.

WIRING-CONDUIT CAP.

Application filed July 18,

1 '0 all whom it may concern Be it known that I, FREDERICK I. J 01in- SON, a citizen of the United States, and resident of Warren, in the county of Bristol and State of Rhode Island, have invented certain new and useful Improvements 1n firing-Conduit Caps, of which the following is a specification.

This invention relates to weather caps for protecting the ends of wire-receiving conduits througlrwhich electric wires are led into a building or the like, and the object of this invention is to provide such a conduit-end, cap or protector comprising a substantially elbow-shaped body member having a rotatable coupling connected to one end thereof and an end guide member of insulating material connected to the opposite end thereof the joint between the body and each of these ends being protected against the action of rain or snow by an overlapping skirt or flangeportion.

With these and other objects in view; the

7 invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims. I

In the accompanying drawings:

Figure 1is a side elevation illustrating my improved protecting cap as applied to a horizontal conduit.

Fig. 2-is a sectional view of the body portion of the protecting member with the porcelain removed.

Fig. 3-is an end view of the body portion with the porcelain and coupling members removed.

Fig. 4-sh0ws a different style of elbow member as connected to a vertically-disposed conduit.

Referring to the drawings, 10 designates the body member of my improved conduit end protector which is preferably formed of cast or molded metal and in substantially an elbow-shape, that is the axes through the different openings are Set at an angle to each other. i The wireentering end of this cap or protector-is provided with an'annular flange 11 which is preferably of greater diameter than the body portion thereof and the bottom face 12 of this flange provides an annular seat against which the inner face 13 of the porcelain or insulating end piece 14 rests.

This flange is provided with cars 15 tapped to receive one or more. bindin Specification ofi I.etters Patent. Patented Ju ie 21, 1921 1919. Serial no. airme.

I 6 screws .16.-

It will be noted by this construction that the flange 11 as it is set to project in a down ward direction, serves as a skirt to cover the joint betweenthe porcelain end piece and the body of the on the body portion, and a thimble or ferrule 21 of suitable, bendable material is provided having its opposite edges swaged over the two inturned flanges 17a11d20 to loosely connect this coupling member to the body whereby the coupling member may be rotated to engage the threaded end ofthe conduit 22 without being obliged to rotate either cap, so as to effectually prevent molsture from working through the.

coupling member'is threaded on its ini the conduit or the cap thus greatly facilitating the gether.-

I have shown and described the coupling as connected to the cap by a separate thimble, but any suitable means may be employed for connecting together these two members. It is found in practice that where such a connection is made, that it is quite necessary to provide a skirt, flange or overhanging lip 23 to exclude the weather from this joint and protect the same by positively preventing the entrance of either snow or rain through this oint. 7

Even with this overhanging skirt it is found that in some cases driving storms will work under the overhanging skirt and I have, therefore, cut away this flange 23 at its bottom portion 2 1 so that any water which may work under the flange will run out connecting of these two members tothrough this opening and prevent the ac pair'of ears and two binding screws ar ranged to retain the porcelain member in the cap, while in Fig. 4 I have shown a lip 25 which is adapted to engage one edge of the flange of the porcelain member while the op posite side of the porcelain member is retained by a single screw 26.

My improved construction of conduit end protector is very simple, practical and inexpensive and may be very readily applied to a conduit, and at the same time is designed to efi'ectually protect both the end of the con duit against the entrance of moisture, and thus prevent short circuiting of the wires, which might otherwise result from freezing.

The foregoing description is directed solely toward the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. A wiring conduit cap comprising a substantially elbow-shaped body having a socket ing flange on said body extending over the joint between it and said coupling.

2. A wiring conduit cap comprising a substantially elbow-shaped body having an an nular out-turned flange for incloslng and providing a seat for a removable insulating end piece, the opposite end of said body having an inwardly projecting flange, a coupling member rotatably connected to said flange, a weather shielding flange on said body extending over the oint between said coupling and its seat, and said weather shielding flange being provided with a drain opening.

In testimony whereof I aflix my signature.

FREDERICK I. JOHNSON.
